QTM216J-10.000MDJ-T

Overview

The QTM216J-10.000MDJ-T is a surface-mount crystal oscillator manufactured by QST. It operates at a fundamental frequency of 10.000 MHz with a standard output waveform type of CMOS. The device supports a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2mm x 1.6mm. The unit exhibits a frequency tolerance of 50ppm and is designed for applications requiring precise timing signals in space-constrained electronic systems.

Feature Summary

• CMOS output waveform provides digital signal compatibility
• Integrated enable/disable functionality for power optimization
• Compact 4-SMD no-lead surface mount footprint

Applications

• Portable consumer electronics
• Communication modules
• Embedded computing systems

Procurement Notes

Verify the specific suffix 'MDJ' against the manufacturer's official documentation to confirm the 1.8V operating voltage and 50ppm tolerance specifications. Ensure the ordering part number matches the required frequency and package style. Cross-reference the datasheet for environmental ratings and reliability data before finalizing procurement decisions.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small 2mm x 1.6mm footprint. The CMOS output is suitable for direct interfacing with digital logic inputs. Consider the 50ppm tolerance if higher precision is needed, as other variants may offer tighter stability. Verify the enable pin requirement fits the system power sequencing design.

Part Context

This oscillator belongs to the QTM216J series from QST, which offers various frequency and voltage options within a standardized small outline package. The series is designed to replace larger through-hole or older surface-mount oscillators in modern portable devices. Variants within the series differ primarily in frequency, supply voltage, and tolerance, sharing the same physical envelope.

Replacement Considerations

Direct replacements include the QTM216J-10.000MBJ-T, which shares the same frequency and package but operates at 3.3V instead of 1.8V. Other compatible frequencies in the same package include 11.2896MHz variants such as the QTM216J-11.2896MBJ-T. Ensure voltage compatibility when substituting.
